Question

Answer 1

您的json文件 ("/something/abc.json")

{"employees":[
    {
        "firstName":"Ray",
        "lastName":"Villalobos",
        "joined":2012
    },
    {
        "firstName":"John",
        "lastName":"Jones",
        "joined":2010
    }
]}

您的PHP代码，

<?php
$string = file_get_contents("/something/abc.json");
$arr = json_decode($string,true);

foreach($arr as $a)
{
    // Iteration
}
?>
